Question

Image text transcribed for accessibility:Write a function called DNAcomplement that consumes a set of letters as a character array that form a DNA sequence such as 'gattaca' . The function will produce the complement of the sequence so that a 's become t 's, g ' s become c 's, and vice versa. The string 'gattaca' would therefore become 'ctaatgt' . You may assume that all the letters in the sequence will be lowercase and that they will all be either a, t, g, or c. Note: You may be tempted to use iteration for this problem, but you don't need it.
